VIND Silenced Inline Fans & Climate Controllers
VIND is our own line, built for one job: moving real air through a house without anyone noticing it is running. Every fan is an EC motor with PWM speed control, suspended on vibration-damping springs inside a fully insulated 40–50 mm acoustic chamber. The silencing is part of the fan, not something you buy afterwards and bolt onto the duct.
It is designed for Australian subfloors, roof spaces, garages and grow rooms, and it is backed here in Sydney rather than by an overseas brand office.

The comparison worth doing before you buy.
Quietening a standard inline fan means buying the fan, then buying a silencer to put in the duct behind it. On a 150 mm setup that is a Cloudline PRO S6 at $269.95 plus a 150 mm inline silencer at $149.95 — $419.90, and a longer run to find space for.
The VIND 150 mm is $229.95 with the acoustic chamber already around the motor. That is the argument for the range in one line.

Pick by the space
| Smaller subfloor, short direct run | VIND 150 mm — 480 m³/h, 583 Pa, 41 dB, 42 W |
| Larger subfloor, long or bendy run | VIND 200 mm — 995 m³/h, 656 Pa, 47 dB, 90 W |
| Starting from nothing | 200 mm kit — the fan plus the first metre of acoustic duct in one order |
| Conditions that swing | Temperature & Humidity Controller — runs the fan only when it will achieve something |
Length and bends cost airflow, so a difficult run wants the bigger fan even where floor area alone would not say so. Send us the dimensions and how the duct has to travel and we will tell you which one fits — an oversized fan turned down is quieter than a small one flat out, so erring upward is rarely wrong.
A fan is only half of a quiet install
People buy a quiet fan and are surprised the install is still audible. The reason is that a fan makes noise in two places and only one of them is the motor. The other is air moving at speed down a thin foil duct, which carries sound along the run and radiates it wherever the duct happens to be.
Our acoustic ducting is the answer to the second half — a perforated aluminium inner core inside a 26 mm wall of high-density glass wool, rated by the manufacturer at up to 50% noise reduction. One metre placed straight off the fan outlet does most of the work, because that is where the noise is loudest.
It is standard ducting dimensionally, so it fits AC Infinity Cloudline fans as readily as ours. If you already run a Cloudline and want it quieter, a metre of this is the cheapest useful thing you can do about it.
Control without an app
Every VIND fan ships with a manual PWM speed controller — set a speed, it holds it, nothing to pair. The VIND Temperature & Humidity Controller takes its place when you want the fan making its own decisions, with independent temperature and humidity thresholds, auto and timer modes, alarms and a 3 m sensor probe.
It is direct-wired. No WiFi, no Bluetooth, no account, no firmware updates. For a fan installed under a floor and expected to work in five years without being maintained, that is a feature rather than a limitation.
When AC Infinity is the better buy. If you want your fan on the UIS system alongside a controller, sensors and an app — VPD targets, logging, remote access, everything talking to everything — that is what the Cloudline range is built for and VIND does not compete with it. VIND is for the install where you want strong, quiet airflow and nothing to manage. Both are good answers to different questions, and we sell both, so we have no reason to push you the wrong way.
